R Code.

A list of useful R code for Master, PhD and Post Graduate 

List of R Code Used by E3B Graduate Students

Graphs and Figures:
Commands for different graphs:​​
  • plot(x-value, y-value): used to create a scatter plot
  • hist(vector_name): used to create a histogram 
    • To plot density instead of frequency, add freq = False in the parentheses
  • barplot(x-value, y-value): used to create a bar graph
  • lines(x-value, y-value): used to create a line graph
  • boxplot(y-value~x-value): used to create a box plot

Commands to edit figures:
  • main = "Title": used to set the title of the figure
  • xlab = "X axis": used to set the title of the x-axis
  • ylab = "Y axis": used to set the title of the y-axis
  • col = "color": used to set the color of the data points/bars/etc. of the figure
  • xlim = c(min, max): used to set the range for the x-axis
  • ylim = c(min, max): used to set the range for the y-axis

General Tips:
  • To specify which x or y values to use, you can either use dataset$column_name or specify the column names and add data = dataset within the parentheses (ie. "plot(dataset$column1, dataset$column2)" or "plot(column1, column2, data=dataset)")
  • The package "ggplot" can be used to create more detailed figures with more ways to edit them
